Whakaoti mō b
b = -\frac{19}{4} = -4\frac{3}{4} = -4.75
Tohaina
Kua tāruatia ki te papatopenga
4b=-18-1
Tangohia te 1 mai i ngā taha e rua.
4b=-19
Tangohia te 1 i te -18, ka -19.
b=\frac{-19}{4}
Whakawehea ngā taha e rua ki te 4.
b=-\frac{19}{4}
Ka taea te hautanga \frac{-19}{4} te tuhi anō ko -\frac{19}{4} mā te tango i te tohu tōraro.
